2. In the downloaded file you might find one or two packages that support different PHP versions.

In the most recent versions of the module, you will find only one package that supports PHP 7.1 and later.
If you need a package for the previous versions of PHP, please contact our support.

Previous updates of the module may contain two packages dedicated to various PHP versions.

The first one that supports PHP 5.6 up to PHP 7.0, and the second one addressed to PHP 7.1 up to PHP 7.3.
Note: Keep in mind that PHP versions 5.6 up to 7.0 are no longer officially supported and their security issues are not fixed or released any more. Find more info here.

Important: This situation does not affect the open source version of this module which can be applied to any PHP from version 5.6 and later.
Note: You can check the current PHP version in your WHMCS. To do so, proceed to 'Utilities' → 'System' → 'PHP Info'.
3. Once you have chosen the package with the right PHP version, extract it and upload its content into the main WHMCS directory.

The content of the chosen PHP version files to upload should look like this.

Configuration and Management

In this section we will show you how to properly set up and use Hosting Quota Notifications For WHMCS to its full potential.


Dashboard of the addon includes statistics on the module actions attempts, either successful or failed.
  • Successful actions - marked in green - take a look at the number of emails sent, tickets opened and products suspended or terminated in the provided time periods.
  • Failed actions - marked in red - the module could not perform enumerated here actions due to external issues, for example: server errors (cannot suspend account), SMTP errors (cannot deliver email), etc.
    For more details on failed actions please refer to the logs section.
HQN2 29.png


This is a primary section which allows to create numerous rules according to which the services resource usage will be monitored and calculated and then adequate notifications sent.
HQN2 9.png

Rule Configuration

Let us begin with creating an exemplary rule according to which disk usage of selected service will be checked.
Press 'Add Rule'.
HQN2 10.png
Start with typing a custom name, selecting the usage calculating type: 'Tiered' or 'Fixed' (read more about these two methods here).
Choose your products that this rule will cover.
HQN2 11.png
Once you have saved the changes, you will be moved to the rule configuration page.

Here you may:

  • Set the status of the rule to 'enabled' or 'disabled' .
  • Change the name of the rule.
  • Manage the types: 'Tiered' or 'Fixed' .
  • Assign products from available.
  • Select a default email template that will be sent to a client with notification. Set to 'None' to disable the option.
    You may use the predefined custom template ('Service Usage Limits Notification') implemented in the module or prepare your custom one. Find out more in this section.
  • Set notification hourly interval to send the notifications.

Save the changes when ready.

HQN2 12.png

Steps Configuration

Move to the next tab - 'Disk' to define steps conforming to which the usage will be verified.

Press 'Add Step' to begin.

HQN2 13.png
  • Start with selecting a Unit type: 'MB', 'GB', 'TB' or 'Percentage' .
  • Provide numerical value, e.g.: 20 (depending on the unit selected it will be: 20MB, 20% etc.)
  • Period (Days) - number of days when the resource usage will be verified - (Fixed type only).
  • Email Template - select one per single step, if you choose 'default' then the one selected at the rule configuration will be used. Choose 'None' to disable the option.
  • Ticket Template - if you want to notify a client in form of an opened ticket, select the template here or set to 'None' to disable.
  • Action - you may automatically 'Terminate' or 'Suspend' a service once selected limit has been reached.
    Set to 'None' if you do not want to trigger any action on the service.
HQN2 14.png
Surely, you may add more steps for the same rule and force different actions on the services.

You may edit the steps if needed or delete them.

HQN2 15.png
Configure the steps for 'Bandwidth' usage limits in the very same way as in case of the described above 'Disk'.
HQN2 16.png

Calculation Methods

As mentioned above, there are two calculation types available: 'Fixed' and 'Tiered'. We will try to explain now the main differences between them and show an example of a full calculation.
  • Fixed type - resource usage calculated within a selected time period defined in the 'Period (Days)' field.
  • Tiered type - full amount of resource usage.
Take a look at the table below to see the differences between these two types.
Day Usage
Day 1 10 MB
Day 2 20 MB
Day 3 10 MB
Day 4 5 MB
  • For Fixed type:
    Period: Last 3 days
    Value: 30 MB
    Take the three last values from the Usage column, the sum of 20, 10 and 5 gives 35.
    30 MB limit has been exceeded during 3 days, therefore a notification is sent.
  • For Tiered type:
    Value: 40 MB
    Take the sum of values from the entire Usage column, 45 MB in this case.
    40 MB limit has been exceeded, therefore a notification is sent.
Apart from the calculation type, you must also select a unit - MB, GB, TB or percentage.
  • If you select any of MB, GB, TB and 20 as value, such amount of resource usage will be taken into consideration for every assigned product.
  • If you select 'Percentage' and 20 as value, then 20% of the set in WHMCS soft limit will be taken into consideration for every assigned product.
    For example, if in WHMCS the service limit is set to 100 MB, then 20% calculated from 100 gives 20 MB - this amount of resource will be considered for this single product.

Ticket Templates

The 'Ticket Templates' section gives you the opportunity to create as many templates that will be used to open informative tickets as needed.
Press 'Add Ticket Template' to create one.
HQN2 17.png
Type in the ticket template name, select a support department and support administrator to which the ticket will be automatically assigned.

When ready, save changes.

HQN2 18.png
You will be immediately moved to the template configuration page where you can again rename it as well as change the department.
HQN2 19.png

Ticket Template Translations

Next, you need to proceed to the 'Template Translation' section. There you can provide the content of the template.

Press 'Add Template Translation'.

HQN2 21.png
Enter a template name, select language and type in the text in the 'Message' text field.
If you select default language, then this template will be used in case there is no translation in the client's language.
HQN2 22.png
There are numerous merge fields that you may use in the message to make it full and most informative.
As you can see at the bottom, there is a list of special merge fields particularly designated for notifications. These are:
  • Notification Limit - displays the allowed resource usage limit.
  • Notification Usage - stands for the current resource usage of the client service.
  • Notification Kind - returned as Bandwidth or Usage.
  • Notification Unit - returned as MB, GB or TB.
  • Notification DifferenceUsageAndLimit - amount by which the limit has been exceeded.
  • Notification PeriodDays - period of days when the usage is verified defined for 'Fixed' type.
HQN2 23.png
Use action buttons to edit or delete the template translations.
HQN2 24.png
That is what such an automatically opened ticket may look like in your client area.
HQN2 24 1.png


Another section that we need to draw your attention to is called 'Services'.
You will find there products which are included in any of your configured rules with disk or bandwidth usage.

Press the icon marked on the screen below and you will get details on the current resource usage of the service per each day.

HQN2 25.png
Check out the statistics on the disk and bandwidth usage per single product.

Please note that WHCMS updates the quote and traffic load once a day only.

HQN2 26.png


Under the 'Logs' page you can view information about sent notifications via email, opened tickets, errors, performed actions etc.
HQN2 27.png


1. There is one default email template that may be used to send email notifications. Find 'Service Usage Limits Notification' at WHMCS → Setup → Email Templates → Product/Service Messages.

You may edit the template freely, using special merge fields and create new ones on its basis. Allowed module special merge fields:

  • {$kind} - stands for bandwidth or usage.
  • {$limit} - allowed resource usage limit.
  • {$unit} - MB,GB or TB.
  • {$usage} - current resource usage of the client.
  • {$differenceUsageAndLimit} - amount by which the limit has been exceeded.
  • {$periodDays} - period of days defined for 'Fixed' type.
HQN2 30.png
That is what the email message may look like when delivered:

2. When configuring a ticklet template you need to select an admin to which it will be assigned. However, the ticket will be automatically opened by a randomly selected administartor.

Update Instructions

An essential guidance through the process of updating the module is offered here.

Common Problems

1. When you have problems with connection, check whether your SELinux or firewall does not block ports.
